UNITED STATES PATnNT YAPPARATUS FOR DRYING STEREOTYPEJNIATRICES.

SPECIFICATION' forming part of Letters Patent No.331-,5l-4, dated January 19, 1836.

Application filed July 13, 1885. Serial No. 171,417. (No model.) Patented in England May 20, 1884, No4 7,959.

T0 all whom t may concern.-

Beit known that I, GUIsnrrE PEP, a subject of the King of Italy, residing at Beresford Street, Valworth, in the county of Surrey, England, stereotyper, have invented certain new and useful Improvements in Apparatus for Drying Stereotype Matrices, (for which I have received Letters Patentin Great Britain, No. 7,959, dated May 20, 1884,) of which the following is a specification.

For this purpose I employ a hollow drum, upon the exterior surface of which I arrange a number of hinged clamping-frames to hold the matrices in contact with the drum. The drum is made with projections or ribs to actin combination With hollows in the clamping-frames, orvice versa. The drum is mounted in a casing With capability of revolving upon a hollow axle,through which steam is introduced into the interior of the drum.

At some convenient part or parts of the apparatus I arrange a flre,and I conduct the products of combustion therefrom through a flue carried partially or entirely around the exterior of the drum and near to the stereotypematrices clamped thereon. In the casing I advantageously employ an outlet or outlets for the escape of moisture driven off fromthe stereotype-matrices.

The lire or res may be employed to melt the metal required to produce the stereotype, and with this obj ect I arrange one or more meltingpots at some Convenient part ofthe apparatus.

In some cases I dispense with' a special fire for the apparatus, and pass through the `flue around or partly around the drum heated air or products of combustion obtained from other sources.

By the use of my improved apparatus the production of stereotype-matrices for newspaper and other printing is very greatly facilitated and cheapened', as thetime employed in drying the same is greatly reduced, while by the peculiar form and action of the apparatus the buckling or unequal drying and shrinkage ofthe matrices is prevented.

My invention also enables me to retain in positionin the matrices the pieces of card-board employed to retain the form of the White spaces, so that when the matrices are dried they require only little finishing.. tained by clamping the matrices onto the re- This effect is obl bars b2.

volving drum with their backs toward the drum, the pieces of card-board in the White spaces being also in contact with the drum, and thereby heldin position during the drying operation 5' and iu order that my said invention may be more clearly understood and readily carried into effect, I will proceed, aided by the accompanying drawings, more fully to describe the same.

In the drawings, Figure I is a vertical section, and Fig. 2 is a sectional plan, of apparatus constructed according to my invention. Figs. 3, 4, and 5 are detail views, and Figs. 6 and 7 are views drawn to a larger scale showing a piece of card-board in position to form a White space.

i a is ahollow drum, upon the exterior surface of which are arranged a number of hinged clamping-frames, b, to hold the matrices in contact with the drum c. The drum a, as shown at Fig. 5, is formed with grooves or hollows a', to act in combination with the sides of the clamping frames b, in order to facilitate the holding of the matrices in position. The drum c is provided with hollow necks or axes a2, which are mounted in bearings c on the sides of the casing c, and through stufngboxes a3 on the ends of such necks or axes a2 are passed stationary pipes d e, steam being admitted into the drum through the pipe d, and passing away therefrom through the pipe e.

At some convenient part or parts of the apparatus I arrange a fire-place, f, and Iconduct the products of combustion from the fire therein through a iiue, g, carried partially around the exterior' of the drum a, as shown in the drawings, (or it may be entirely around the same,) and near to the stereotype-matrices clamped thereon. In the casing c,I arrange outlets c2 vfor the escape of moisture driven off from the stereotype-matrices, and such moisture is circulated by means of wings a", and is drawn through such outlets c2 by the draft in the flueg. The lire or fires may be employed to melt the metal required to produce the stereotype, and with this object I arrange one or more melting-pots on thetop ofthe tire-placef, or atsome other convenient part of the apparatus.

The clamping-frames b are advantageously made, as shown, with outer bars, b', the end ones of which are connected together by cross- Such frames b are provided With IOI) projections b, which pass through eyes a4 and act as hinges, while they are also provided with catches Z, which aet,in combination with eyes or hooks a5, to hold the said clampingframes, and consequently the matrices rmly against the cylinder a. The drum e in its interior is provided with cups a, which act o lift the water of condensation, and on the same falling it is carried away by the steam through the trumpet -shaped pipe c', iixed to the pipe e. Other suitable means may, however, be employed for carrying off or discharging the condensed water. The upper part of the easing c is hinged, so as to enable it to be thrown back into the position shown by dotted lines in Fig l, when itis de sired to apply the matrices to or remove them from the cylinder (l. At other times such upper hinged part of the casingb is placed in the position show 11 by the full lines.

The drum a is provided with a pulley, el, by which, aided by a Strap or band, it maybe rotated during the drying operation, while it is also provided with a hand-wheel, ai, by which, when not driven by the band, it may be turned to the required position for placing the matrices thereon or removing the same therefrom.

At Figs. G and 7 I have represented the means advantageously adopted i'or retaining the form of the white spaces. h represents the stereotype-matrix, which is clamped with its buck toward the drum a, and i a piece of cardboard to form a white space, which is placed between the matrix and the drum a, and is connected tothe back of the matrix, and is thereby held in position during the drying 0peration.

Having now particularly described and ascertained the nature of my said invention, and in what manner the sume is to be performed, I declare that what I claim is- 1. The Combination, in an apparatus for drying stereotype-molds, ofa rotary drum, clamping frames carried by said drum fortheattaehment thereto of the molds to be dried, and a surrounding easing for the circulation ot' air around said drum and the attached molds, Substant-izfilly as herein described.

2. The combination of the rotary steamheated dru n1 a, the clamping-frames Z1, attached to said drum, the easing e, surrounding said drum and having outlets c2, and the ilue partly surrounding said easing and communicating with the interior thereof through the outlets c2, substantially as herein described. l
